Hi everyone, 
I would like to activate CIC_Mid through Patch and fake FSC. 

It is known that the Patch from Intel123 only works with Professional units. However, you can find information on the forum that some guys have managed to activate CIC_Mid as well. Unfortunately, apart from the words themselves, I couldn't find anything else. Therefore, I wanted to take a closer look at the issue and try my hand at it. 

My findings at the moment are: 
1. Patch does not run via USB (What can be found on the web is confirmed)
2. Library error when trying to run Patch in Shell 
3. Swap of the Root certificate works until the CIC is restarted

It seems that there is also an rcert control mechanism in CIC_Mid, which replaces it with the original one if changes are detected. I also suspect that Patch doesn't work because the filenames in the CIC_Mid are different. The Cid_Mid are "CicMidNavRoot" and "CicMidNavSecond". I probably need to turn off control. Intel123 did this by changing two bytes in fs0. I'd like to do it here, but it begs the question, do I need to do a checksum correction when changing these bytes? If yes, how? I think that disabling the control would be enough to be able to replace the root certificate and upload the fake FSC to your VIN.
